Hi, I'm a first time Arduino user. I just got my Arduino in the mail. I purchased it through Banggood. When I plug in my Nano 3.0 the red L LED flashes several times a second. Also, the Arduino IDE does not recognize it. When I go to Tools -> Serial Port, all I get are four Bluetooth ports.
I tried installing the FTDI drivers at VCP Drivers - FTDI
However, even after doing this and restarting my computer the Arduino is not showing up at Tools -> Serial Port. I am using a MacBook Air.
This problem has been solved. ChilliTronix's answer at http://forum.arduino.cc/index.php?PHPSESSID=59n11leh8astqtcho5a2o03051&topic=277611.0 worked for me.
